I don't trust ANY Motor Trend figures. They have been in the back pocket of Detroit from way back.
I also don't think magazine figures were very accurate. How many factored temp,humidity, altitude and stock tires into the equation? Not to mention driver differences.
How many of the above ET quotes factored in those figures?
I think todays mags do a better job of it.
If you are quoting old magazine figures. Then you really don't know the truth.
Top Gear does some of the best work on track testing cars. They use the same driver and track for their comparisons.

Back in the day in Northern California, you could count on a stock Hign Performance big block turning mid 12's (3.70:1) and it wasn't all that unusual to see high 11's. These were numbers from average street Corvettes, not full on NHRA prepped cars.
We had blueprinted a 1966 425 HP 427, adding L-88 pistons, headwork, headers, but still running the original single four-barrel carburetor, M&H drag slicks, 4.56 or 4:88 rear end, drag front tires and we were running mid 10's.
Also had a 1969 Corvette 311 cu in (de-stroked 350 cu in, .030" over-bored) running a tunnel ram and two 660 cfm double-pumper carburetors, Stahl headers, Slicks, skinny fronts, etc., fully prepared running in D/MP. This car ran low 10's and would consistently devastate the locals who were sure that it was a 454!
Surprise it's a Mouse!
